Ordered structures in GaAs0.5Sb0.5 alloys grown by organometallic vapor phase epitaxy
TL;DR: In this paper, electron diffraction measurements on (100) GaAs1−xSbx layers with x≊0.5 grown by organometallic vapor phase epitaxy indicate that ordered phases are formed during growth.

On spinodal decomposition in elastically anisotropic epitaxial films of III‐V semiconductor alloys
TL;DR: In this paper, the elastic energy associated with alloy composition modulation in the epitaxial film of a III-V semiconductor alloy on the [001]−substrate is calculated in the analytic form.

Thermodynamic aspects of OMVPE
TL;DR: In this article, a simple model is developed which assumes thermodynamic equilibrium to be established at the solid/vapor interface, which can be used to understand the growth rate limiting process, the conditions necessary to grow a single phase III/V material, and the factors determining solid composition.
Journal ArticleDOI
Ordered structures and metastable alloys grown by OMVPE
TL;DR: In this article, it was shown that the relative strain energies of the various ordered structures at the surface and/or kinetic processes occurring during epitaxial growth indicate that such ordered structures are more stable than the disordered solid solution, but less stable than other ordered structures.

On spinodal decomposition
TL;DR: In this article, the stability of a solid solution to all infinitesimal composition fluctuations is considered, taking surface tension and elastic energy into account, and it is found that for infinite isotropic solids, free from imperfections, the spinodal marks the limit of metastability to such fluctuations only if there is no change in molar volume with composition.

Calculation of ternary and quaternary III–V phase diagrams
TL;DR: In this paper, a simple solution model with Ω=a−bT was used to describe the liquid phase and the solid phase was adequately described using the regular solution model.

Miscibility gaps in quaternary III/V alloys
TL;DR: In this article, the critical temperatures for all III/V quaternary alloys of the type AxB1-xCyD1-y involving Al, Ga, and In combined with P, As, and Sb were derived using both the DLP model and regular solution model.

The importance of lattice mismatch in the growth of GaxIn1−xP epitaxial crystals
TL;DR: In this paper, the importance of lattice-parameter mismatch between the GaAs substrate and the GaxIn1−xP epitaxial layer on crystal growth and properties has been investigated.

Composition modulation in liquid phase epitaxial InxGa1−xAsyP1−y layers lattice matched to InP substrates
TL;DR: In this article, a quasiperiodic variation of a strain contrast, though very light in some cases, is always observed in the 〈100〉 and 》010〉 directions in that composition range, and never outside.
